FOLLOWING WORK REST.

Application filed December 26, 19227; SerialNo. 608,970.

To all 'w 710m t may concern."

Be it known that I, JOSEPH L. SCHMID- LING, a citizen of theUnited States, andl resident'of Milwaukee, in the county of'Milwaukee and State of Wisconsin, have invented newrand useful Improvements inV Following Work Rests, of which the follow-- ing isa description, reference beingha'd to` they accompanying drawings, which are a' part of this specification. v

This invention relates to Jfollowing work rests and has for one of its objects to provide a device of this character whichis particularly adapted for permitting the turning of rods or wires of relatively small diameter. f l A further'object of the invention is t0v provide a device kof the character described `which is adapted to be mounted upon an ordinaryT lathe or other similar turning machine. f'

A still further object of the invention is to provide a device for supporting the wire orrod immediately'adjacent the porton being acted upon by the cutting tool, and for feeding the said wire or Irod'relative to the said supporting and cutting tool, whereby the said work may 'always be supportedat that point.

A still further object of the invention is tovprovide a device which may be readily applied to or'rcmoved, ffrom machines whichare already 1n use', 'and which will be simple Y w inl construction, comparatively inexpensive to manufacture andmore `efficient in operation'tha'n those which have been heretofore proposed'.

Withthe above and other objects in viewVv which will appear as the description proceeds, the 'invention consists in the novel, de-

tails of construction and combinations lof parts more fully hereinafterdisclosed andv particularly lpointed out inthe appended invention;

mately on the line 2"-2 of the said Figure;

Fig. 3 is a vertical cross-sectional view taken approximately on the line 3-3 of r Fig. 1; and,

Fig. 1 is a fragmentary longitudinal sectional view of a somewhat modified form of the-invention. f Referring more especially to Figs. 1, 2 and 3, the numeral 5 indicates a supporting block yor member of any desired shape, here shown as a substantially rectangular block. The

Vsaid member 5 is provided upon its lower end with a depending tongue 6, adapted to engage a groover or guideway on ythe lathe or other machine to which the rest may be applied, and the said member 5 is further provided with a. longitudinal bore 7 in which isslidab'ly mounted a tube or sleeve 8. TheA said member or ,block 5 is preferably providedwith a saw cut or slit 9 in its upper portion abovev the bore 7, and a clamping bolt 10 passes through the oppositely disposed portions of the said block whereby the said sleeve or tube 8 may be rigidly clamped within the said bore in any desired position.

Slidably mounted within the bore 11 vof nthe tube 8 is a plunger or mandrel 12, pro- `clear from Fig. 2. The said mandrel 12 is adapted to be held against longitudinal movement by` means of a screw or pin 16, carri-ed by the block 5 and passing through lan elongated slot 17 in the sleeve 8, into the said mandrel 12, (see Figs. 2 and Rigidly secured to the end of the sleeve 8 and opposite to the mandrel 12is an anvil 18 provided with a bridge 19, carrying a `-clamping` screw 20 which is adapted to clamp the wire or rod 21 in position within the bores 11 and 13,v as will be clear from Fig. 2; Y Y

Secured to the said anvil member 18 is an extension rod 22 to the outer end of which is pivotally connected as at 23 the handle lever 24. One end of the said lever 211 is pivotally connectedfasv at -25 to one end of a link 26, the other end of which is pivoted as at 27 to a supporting member 28, rigidly secured to the block 5 as by the bolts or screws 29.

In operation, when it is desired to reduce the diameter of a wire or rod, such as 21, the said wire or rod is introduced through thebores 11 and'13,` through the wire-holding member 14 with its extreme end projecting a slight distance beyond the said member 111, and it is clamped in this position by means of the clainpingscrew 20, engaging the said wire and binding it against the anvil member 18. The clock 5, being in position upon la lathe or other turning machine and suitable secured thereto to'present the extending end of the wire or rod 12 to a suitable revolving cutting tool 30, the handle member 2st is grasped and moved toward the lert, as seen in Fig. 1, which motion is transmitted to vthe extended rod 22 andto the anvil member 18. The said anvil 18 and tube 8 will therefore be moved longitudinally of the bore 7 carrying with them the wire or rod 21 and forcing the latter to be fed throughthe wire-holding member 14, as will vbe readily apparent..

As the wire is thus fed, it is acted upon -by the 5revolving cutting member 30, whereby its `diameter iis reduced to any desired dimension.

Duringthis operation Vthe clamping bolt 10 has been loosened to permit the free movementof the sleeve 8 within the bore 7,

and the lmandrel 412 has been rigidly secured against axial movement by reason of its set screw connection 16 with the block 5.

1When the 'length of wire within the device has been acted upon 'by the cutter member 30 the parts maybe returned to their initial positions illustrated in Figs. l andy 2 and an additional length of wire fed forward or afnew piece put in.

In the lform of .the `invention shown in Fig. 4 provision' is made for the rotation of the wire and the wire-holding feeding member, -as well as for the automatic re-v wire or rod material is fed, and in. which it is clamped by means of a set screw 32. The entire device is rotated in any' suit-l able manner andas the sleeve 8 is fed forward, it carries with it the wire or rod 2l, causing it to come -into Contact with the stationary cutting tool 35, which will reducefits diameter to any desiredgdimension. The parts will be returned-to their intial positions by vthe spring 3l when the feeding means is released.

ln both forms' of the invention the cutting tool is rlocated immediately Vadjacent the end of the mandrel 12 so that its blade engages, the wire or rod 21, very close to thewire-holdmg -Jaw 13 to the end thatk the said aw may properly support the rod and yprevent the bending thereof. It results from thisconstruction that wires or rods of relatively small diameters may be produced in a lathe or other turning niachine, and in actual practice wires as line as .0l and even .005 of an inch have been produced from rods or wire of of an inch in diameter or more. it will, of course be understood that the removable wire-holding members 14 are changed to accommodate stock material of different diameters so that the said stock will just slide through the bore of the said members let freely, at the same time being fully supported by the said members.

lVhile two forms of the invention have beenY illustrated and described it is obvious that those skilled in the art may vary the details of construction as well as the arrangement of parts without departing from the spirit of the invention, andl therefore it is not wished to be limited tothe above disclosure except as maypbe required vby `the accompanying claims.

' 'Yliat is claimed is:

1. A device of the class describedcomprising a substantially rigid supporting member provided with a bore; a work feeding member slidably mounted in saidbore; a work holding and supporting member carried by said iirstvsupporting member, adapted to rigidly support said work in close proximity to a cutting tool; and ,means for sliding said feeding member for feeding the work through said worksupporting member to said tool.
